Answer 1

Answer:

this your answer

Explanation:

Answer 2

Given:

The frequency of the photon, ν = 3 × 10¹⁵ Hz

To Find:

The energy of the given photon, i.e., E.

Calculation:

- The energy of a photon is calculated by the given formula:

E = h × ν

- Putting the value of h = 6.63 × 10⁻³⁴ and frequency, we get:

E = 6.63 × 10⁻³⁴ × 3 × 10¹⁵

⇒ E = 19.89 × 10⁻¹⁹ J

⇒ E = (19.89 × 10⁻¹⁹)/ (1.6 × 10⁻¹⁹)

⇒ E = 12.43 eV (approx)

- So, the energy of the given photon is 19.89 × 10⁻¹⁹ J or 12.43 eV.
